Portal hypertension waveform
Portal hypertension is defined as a hepatic venous pressure gradient (HVPG) >5 mmHg. Hepatic venous pressure gradient is a surrogate for the portosystemic pressure gradient. Clinically significant portal hypertension is defined as a gradient >10 mmHg and variceal bleeding may occur at a gradient >12 … See more Causes can be split by their relation to the hepatic sinusoids 7: 1. portal vein thrombosis 2. extrinsic compression of portal vein 3. congenital portal vein stenosis 4. … See more Dilatation of splenic veins at the splenic hilum without splenomegaly may occur in situations such as a state of increased perfusion of splenic tissue associated with an immune response 6.
